S32 of the Civil Liability Act says there is no duty of care unless the defendant ought to have foreseen that a person of normal fortitude might in the circumstances suffer a recognised psychological/psychiatric injury. Circumstances include whether the harm was caused by sudden shock; the plaintiff witnessed the injury/death at the scene; pre-existing relationship between plaintiff and defendant. There is no duty of care if you were not at the scene unless you were a close member of family of the victim, such as a spouse, parent, child etc.
